Magento – I am getting error on save() method of a model

model

I am getting this error on save method of a model.

Fatal error: Call to a member function beginTransaction() on a
non-object in
/home/public_html/app/code/core/Mage/Core/Model/Abstract.php on line
313

$warranty = Mage::getModel('warrany/warrantydata');
$warranty->setOrderId($order_id);
$warranty->setSignifydScore($signifyd_score);
$warranty->setSignifydData(utf8_encode(serialize($data)));
$warranty->save();

I have this added xml for model

    <models>
    <warranty>
      <class>Website_Warranty_Model</class>
      <resourceModel>warranty_mysql4</resourceModel>
        </warranty>
       <warranty_mysql4>
              <class>Website_Warranty_Model_Mysql4</class>
          <entities>
            <warrantydata>
               <table>warrantydata</table>
        </warrantydata>
          </entities>
          </warranty_mysql4>
   </models>

i also have the collection and model file

class Website_Warranty_Model_Warrantydata extends Mage_Core_Model_Abstract{}

class Website_Warranty_Model_Mysql4_Warrantydata extends Mage_Core_Model_Mysql4_Abstract {}

In your resource model Website_Warranty_Model_Mysql4_Warrantydata you need to add this method :

public function _construct(){
    $this->_init('warranty/warrantydata', 'entity_id'); //the second parameter must be the primary key in your warrantydata table. If it's not `entity_id` then change it
}

and in your model class Website_Warranty_Model_Warrantydata you need this method:

public function _construct(){
    parent::_construct();
    $this->_init('warranty/warrantydata');
}

Magento – Understanding Error in Model save

Here's how I debug.

Read at the source code.

Overwrite your resource model class save method. And log at each conditions.

class Awesome_Cool_Model_Resource_Payment
    extends Mage_Core_Model_Resource_Db_Abstract 
{
    protected function _constructor(){
        $this->_init('awesome_cool/payment', 'txn_id');
    }

    public function save(Mage_Core_Model_Abstract $object){
        // Copy the parent code
        // https://github.com/OpenMage/magento-mirror/blob/1.9.1.1/app/code/core/Mage/Core/Model/Resource/Db/Abstract.php#L416-L466
        // ..........................................
        // ..........................................
        // ..........................................
        // ..........................................
        // ..........................................

        // Log Everywhere
        // Mage::log('Hi5', null, 'mylog.log');

    }
}

Understand the code flow. (Why the code not executed at certain point)

In my case, My issue is for non increment primary key

solution:
protected function _constructor(){
    $this->_init('awesome_cool/payment', 'txn_id');
    $this->_isPkAutoIncrement = false;
}

Magento 1.9 – Fatal Error: Call to beginTransaction() on Boolean

The problem comes from the declaration of the resources and the name used in the models.

So instead of :

<xmpieformbuilder>
    <class>Company_XMPieFormBuilder_Model</class>
    <resourceModel>xmpieformbuilder_resource</resourceModel>
</xmpieformbuilder>

And then in your models you need to call:

$this->_init('xmpieformbuilder/configuration');

That comes from the fact that you declares your entities using the xmpieformbuilder_resource tag.
